Report Your Accident and Help Us Improve Our Bike App

Were you in an accident involving a bike, but never officially reported it to the police? Many bike accidents go unreported, which makes tracking statistics more difficult.

Help make this tool, and our analysis, more accurate. Share details of your previously unreported crash here. Questions? Drop a line! newsapps@baycitizen.org.
